Bisexuality is the sexual orientation which refers to the aesthetic, romantic, or sexual desire for individuals of either gender or of either sex.

Although observed in a variety of forms in human societies and in the animal kingdom throughout recorded history, the term "bisexuality" (like the terms "hetero-" and "homosexuality") was only coined in the 19th century.

Bisexuality Flag

Bisexual people are not necessarily attracted equally to both genders. Moreover, it is possible for a bisexual person to be attracted to all genders but only one sex, or to all sexes but only one gender (note the definition of gender as social/psychological category, distinct from biological sex). Apart from sexual preference, some bisexual people describe their attraction as being based on personality or other characteristics rather than gender. Another view of bisexuality is that homosexuality and heterosexuality are two monosexual orientations, whereas bisexuality encompasses them both. However, some argue that bisexuality is a distinct sexual orientation on a par with heterosexuality or homosexuality
